Genes affected

PRKDC (HGNC:9413): (protein kinase, DNA-activated, catalytic subunit) This gene encodes the catalytic subunit of the DNA-dependent protein kinase (DNA-PK). It functions with the Ku70/Ku80 heterodimer protein in DNA double strand break repair and recombination. The protein encoded is a member of the PI3/PI4-kinase family.[provided by RefSeq, Jul 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Not Available"; Align-GVGD: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 574280). This variant has not been reported in the literature in individuals affected with PRKDC-related conditions. This variant is present in population databases (rs779687004, gnomAD 0.01%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 2666 of the PRKDC protein (p.Pro2666Leu). -
